Impact: Low
Public: 2011-03-30
Bugzilla: 692898: CVE-2011-1487 perl: lc(), uc() routines are laundering tainted data

Details

The MITRE CVE dictionary describes this issue as:

The (1) lc, (2) lcfirst, (3) uc, and (4) ucfirst functions in Perl 5.10.x, 5.11.x, and 5.12.x through 5.12.3, and 5.13.x through 5.13.11, do not apply the taint attribute to the return value upon processing tainted input, which might allow context-dependent attackers to bypass the taint protection mechanism via a crafted string.
